Police say the incident started around 6:30 p.m. on Adeline Avenue and ended between 10:30 p.m. and 11 p.m. The Allegheny County Medical Examiner’s Office was called to the scene.

According to authorities, a man barricaded inside the home reportedly turned the gun on himself.

Police say one of his relatives called 911 earlier in the evening. When they arrived on scene, officials say they attempted negotiations with the man by calling to him over a loudspeaker.

“As I had mentioned earlier, we did respond for a barricaded, suicidal gunman on Adeline Avenue in Mount Lebanon,” said Lt. Aaron Lauth, of the Mount Lebanon Police Department.

Neighbors say they were told to stay inside their homes and not to drive on the street.

“Just pretty much standing outside our houses as a group because a lot of people who live on this street were asked to turn around and park their cars on a nearby street and just stay away from the area,” said Tracy Badolato, a neighbor.

Allegheny County Police Superintendent Charles Moffatt was also called to the scene.
